This invention relates toacompositionfor building blocks and methodof'maki ng; the

composition.

Th P i a y i '5 provide, inamanner as hereinafter. set forth,

a new and improved acompositi'on: suitable for molding into building"blocks,-. tile,;parti-, tionz-board, and the likeybyrmeans of: whicharticles 'of such class may belproducedwhich ,1 are su'ificiently strongfor their intended purposes, extremely light in weight; fireproof,

sound-r absorbing, and which? are adapted to be sawed or drilled.

' 'A further object of the'inventionsis toprovide 'acompositionforibuilding blocks and cheaperingredients wherebyafinished'article the like which: is formed in a manner to perunit theuse of a maximum'proportion of offhigh' quality may be produced at aminimum ofexpenseef" I i i In carrying out the inventiomuse ismade ofdiatomaceous earth; or kieselguhr, hydrated lime, and a binder which maybeiany one or more-of a number of suitable ingr d1ents as set forth; inthe following examples. 1 i 7 Per cent First example 2 D iatomaceousearth I B. drated1ime 14 Rosin or resinous gum; 2
